But with so many products on the market, trying to decide what to use to ensure maximum protection from the sun can also feel confusing. Luckily, our EV experts are on hand to explain the conflicting advice and what formula is best for you…
Mineral vs. chemicalThe first thing to understand is that there are two main types of sunscreen you can buy – mineral and chemical. Mineral sun creams, also known as physical sunscreens, sit on top of the dermis and work by reflecting the sun’s harmful rays. “Mineral sun creams are made up of non-toxic ingredients such as zinc oxide and titanium dioxide,” says EV Expert and Medical Director at Vie Aesthetics, Dr Ioannis Liakas.
“Not only are these ingredients not absorbed into the skin, but they have an excellent safety record.” Providing both UVA and UVB protection, mineral sun creams start working instantly too. They’re also a better option for those with sensitive or acne-prone skin. “Zinc oxide is an anti-inflammatory and calming agent,” says Dr Liakas. This means that using mineral sun cream formulas can actually help soothe conditions such as eczema, rosacea, psoriasis, melasma and acne.”
However, because they sit on the skin, older mineral formulas have always been thicker, creamier and leave a chalky residue on those with dark skin tones.
Chemical sunscreensWith clearer, lighter formulas, chemical sunscreens – aka traditional sun creams – often feel nicer to use on the skin. They also sit better under makeup and are easier to use.
Unlike mineral formulas that sit on top of the dermis, chemical sunscreens work by being absorbed into skin. The active ingredients – such as oxybenzone, and avobenzone – in these products then absorb the sun’s UV rays, before turning them into heat and releasing the heat through the skin. But they don’t work immediately.
“Chemical sunscreen take a minimum of 10 minutes to bond to the skin and then become effective,” says Dr Anna Hemming, EV Expert and Founder and Medical Director of Thames Skin Clinic.
However, in recent years chemical sunscreens have come under fire for not only being potentially harmful to marine life, but also humans. “Oxybenzone in sunscreen has been found to be highly toxic to juvenile corals and marine life,” says Dr Hemming.
Dr Liakas adds: “Many of the ingredients used in chemical sunscreens have been found or are suspected as hormone disruptors, allergens and carcinogens.” And while further research is needed to reach agreement across the entire scientific community, Dr Liakas says the current data alone has prompted “many to opt for mineral sun creams over chemical ones" already.
What’s best for you?With skincare companies working hard to address the chalky, hard-to-apply mineral formulations of the past, Dr Liakas thinks mineral sunscreens trump chemical versions.
“Mineral sun creams are a more effective way of protecting your skin because the ingredients sit on the surface of your skin and act as a filter as opposed to being absorbed into your skin,” he reiterates. “They are also ‘reef safe’ as both the active ingredients, zinc oxide and titanium dioxide, are naturally occurring.”
As for application, apply under makeup and re-apply throughout the day. “Mineral powder SPFs can be re-applied over your makeup,” says Dr Liakas. It’s also important to reapply sunscreen after swimming or excessive sweating to ensure you’re fully protected.
“Reapply every 2-3 hours and before exposure at a minimum and opt for products with a 5-star UV rating, broad spectrum protection and an SPF of 30-50,” suggests Dr Hemming. As for how much to use? A 10 pence size is needed to cover the full face and neck area.
